RESIDUAL CURRENT DEVICE F200 4-POLE 40A 30MA 110V

Residual current devices Residual current devices (RCDs) are the safest devices for detecting electrical leakage currents and tripping them, ensuring protection against electric shocks caused by indirect contact. These devices must be used in series with a circuit breaker or fuse that protects them from potentially harmful thermal and dynamic stresses due to overvoltages. They also function as main isolating switches relative to upstream circuit breakers (e.g., household consumer unit). Benefits • International market approval ensures global safety performance • High-quality performance and attention to detail • Complete range of products and associated details Features • AC-, A-, B-, and AP-R types available to ensure protection against all types of earth fault currents • Rated current 16–125 A This product description is an automated translation of the original Finnish description.
